<h3>What is permutation?</h3>The formula for permutation is given as:
Permutation =
Where:
- n is the total number of objects = 9
- r is the number selected = 3
Substitute into the formula
Permutation =
P( 9, 3) =
P( 9, 3) =
P( 9, 3) = 504 ways
Thus, the number of ways of she can do it is 504 ways

Answer:
(47) c. given
(48) b. definition of complementary
(49) a, m<2 = m<3
(50) d. definition of congruent angles
Step-by-step explanation:
From the given question, the proof can be completed as;
Statement Reason
1. <2 and < 1 are complementary (47) c. given
<3 and <1 are complementary
2. m<2 + m<1 = (48) b. definition of complementary angles
m<3 + m<1 =
3. m<2 + m<1 = m<3 + m<1 3. Substitution property
4. (49) a, m<2 = m<3 4. Subtraction property
5. <2 ≅ <3 (50) d. definition of congruent angles
Therefore,
(47) c. given
(48) b. definition of complementary
(49) a, m<2 = m<3
(50) d. definition of congruent angles
